ast season, when “iZombie” constructed its new reality wherein the U.S. government and the Fillmore Graves corporation team up to keep zombies and humans behind a wall in Seattle, I thought “This can’t last.” As “iZombie’s” fifth and final season (8 p.m. Eastern Thursdays on The CW) opens, we’re starting to see the specifics of why it can’t last. Meanwhile, creators Rob Thomas and Diane Ruggiero-Wright are maintaining their delicate balance wherein Liv Moore (Rose McIver) and newly zombified Ravi Chakrabarti (Rahul Kohli) behave in humorous ways depending on whose brain they most recently consumed.

n the “Buffy” fan Facebook page I frequent, “Chilling Adventures of Sabrina” (Netflix) is often mentioned when someone asks “What’s a new show that’s sort of like ‘Buffy?’ ” It’s hard to resist the comparisons. After all, the nine episodes of Season 1, Part 2 end with (spoilers follow) …

otham” (2014-19, Fox), which aired its final episode Thursday – and will likely draw more fans on Netflix in this age when shows are perpetually “new,” so I’ll discuss it in present tense — won’t be remembered as a top-shelf superhero franchise in this decade of superheroes. But I have to give it credit for being its own thing. It’s one of very few shows where if I hear someone say it’s horrible, and if I hear someone else say it’s great, I agree with both. Sometimes the quality wavers that much within one episode, and also, a lot depends on your mindset when tuning in.

he Punisher” Season 2 (January, Netflix) might be the most violent season of TV I’ve ever seen. I wouldn’t be surprised if the budget listed fake blood and wound makeup as the biggest expense. Some episodes are bleak enough to affect my overall mood for the next day. Still, while the usual Netflix Marvel Cinematic Universe problem of slow pacing is present in the middle episodes, this is overall solid serial storytelling.

hil Spector” (2013), the last film from writer-director David Mamet before what has become the longest filmmaking hiatus of his career, manages to be a compelling murder-trial biopic without digging as far into the case as one would assume. Mamet focuses on building a character portrait of legendary music producer Phil Spector (Al Pacino), someone who is brilliant, strange, mostly off-putting, occasionally terrifying, occasionally kind, and possibly murderous.

razy Ex-Girlfriend” recently wrapped an amazing four-season run with Rebecca Bunch (co-creator Rachel Bloom) deciding to pursue love – as in her love of writing songs, but now she’ll do it on paper instead of in her head. As fans know, not all of the 150 to 300 songs (depending on how you count them) from “CXG’s” run were in Rebecca’s head, meaning that Josh, Greg, Nathaniel, Paula, Heather, Darryl, etc. also did their share of internal songwriting.

’m glad “Cloak & Dagger” Season 2 (8 p.m. Eastern Thursdays on Freeform) started with a “previously on,” because the plot specifics of this show don’t stick in my head – even though I enjoy the experience of watching it. Last season, as I was reminded, found Tyrone/Cloak (Aubrey Joseph) and Tandy/Dagger (Olivia Holt) exposing the evil corporatists at Roxxon. So it’s good that Season 2 has a new plot, and that the duo is comfortable using their primary powers now. (Their secondary powers promise more weirdness, though.)

BS All Access’ new version of “The Twilight Zone” is certainly putting itself out there. Using the name of the revered Rod Serling series (1959-64) that hasn’t lost its cachet despite all the times it has been resurrected (this is the fourth series by that name), the new series is demanding attention but also setting the bar high. The network has made the pilot episode available for free on YouTube. But like the titular “Comedian” of the episode, its confidence is misplaced and unearned.

generally reject reboots of my favorite franchises, but I flat-out love “Roswell, New Mexico,” The CW’s reboot of my beloved “Roswell” (1999-2002). So I should explain why this is. First of all, it’s really well made, with creator Carina Adly MacKenzie and her team showing respect and knowledge of the original material. Secondly, it doesn’t remake the original story; it plays with the same game pieces but has plenty of reasons to exist on its own. Third, it has a distinct title, making it easier to avoid confusion. And fourth, it didn’t cancel an ongoing story in order to start this new one; the original story was wrapped up in books in 2003.
